This stuff is worth a fortune to cosmetics makers if it could be sold.  The best part is that if spare whale spit was collected from the ocean, then the market in ambergris from whale killing could be ended.

Some sort of non-profit group could maybe collect this stuff at sea and use the money for save the whales funding?  Watching whales already keeps them safe from illegal killing, this could fund more watchers, maybe even underwater robotic watchers?  That collect the spit.
